Locate the position of moon on a newmoon day?

2017-07-17 11:42:21

As an amateur astronomer, I wish to locate the position of the moon on the night of a newmoon day, where I was staying - an island (on which I happended to land the same day morning), through which equator passes and where no alamnacs nor calendars/news papaers /any kind of references are present.

As the question tightened the bolts from all the sides, so it is enough if an approximate location of the moon is known/found during the 12 hours night (6:00 hrs PM - 6:00 hrs AM of the next day). No need of locating it exactly !

Can you help me out please !
